Hi,I have a ReadyNAS Duo v2 running v5.3.7. My configuration was Flex-RAID in JBOD, where I had separate c and d volumes. Both drives were 2 TB. I use a second NAS to do the backup through Rsync once a day. Last week, the second hard drive failed. I replaced it with a 3TB one. The problem is the NAS recreated the d volume but only 2TB in size. There is 1TB wasted. How do I do it to have the second volume use the full 3TB?Here is the last lines of user.log Dec 6 18:57:32 NAS-2 RAIDiator: System is up.Dec 6 18:59:45 NAS-2 RAIDiator: New disk detected. If multiple disks have been added, they will be processed one at a time. Please do not remove any added disk(s) during this time. [Disk 2]Dec 6 18:59:56 NAS-2 RAIDiator: A new disk was added to the ReadyNAS. If multiple disks have been added, they will be processed one at a time. Please do not remove any added disk(s) during this time.Dec 6 19:47:20 NAS-2 RAIDiator: Volume d created successfully.Dec 6 20:09:09 NAS-2 shutdown[5869]: shutting down for system rebootDec 6 20:11:15 NAS-2 RAIDiator: System is up.

d1gear, My initial reaction is to backup your data, Factory default with 2tera & 3 Tera inserted,picking JBOD, and creating Volumes again. Let me know of your results. Thanks,Marto

Thanks for the reply. But this is exactly what I wanted to avoid, doing a factory reset. I have few custom stuff running on this NAS such as my DVR and I don't want to reinstall it. Is there anyway I can play around with LVM2 to solve it?

JBOD volumes don't support expansion.raid 1/5/6 volumes are expandable.since you appear to have backups, you should be able to simply remove the offending volume, then recreate a new 3tb volume.

What do you mean by offending volume? As said, I slotted a brand new 3TB in bay 2 and only a 2TB volume was created on it. When I saw that, I removed it, deleted the partitions, re-inserted it again and still, only a 2TB volume gets created by the NAS.

delete the volume via the web volume management page, don't remove the disk.once you remove the 2tb volume, you should be able to create a new 3tb volume in the available space.

Replaces 2TB with 3TB but only sees 2TB

Well, that's a problem. I think the web volume management disappeared somewhere in a Raidiator update some time ago. Anything else?

The Dashboard doesn't have all the options that were present in Frontview. From memory the Dashboard is missing a web-interface for volume management.

I figured out how to get the web volume management in the latest Raidiator. Here is how.

I edited this file /etc/frontview/apache/httpd.conf and removed the # (comment) before each of the following lines:

Alias /oldadmin /frontview/ui/resource/html
<Location /oldadmin>
DirectoryIndex index.html
Options ExecCGI
Include /etc/frontview/apache/Auth.conf
AuthName "Control Panel"
require user admin
</Location>

I restarted apache using this
killall -9 apache-ssl
/usr/sbin/apache-ssl -f /etc/frontview/apache/httpd.conf

Started my web browser and typed <myNASip>/oldadmin

This gave me access to a funny looking web interface... But at least, volume management was present and I was able to delete Volume D and re-created it with 3TB. Haven't rebooted yet. Will post my results once I have them.
